Lottery officials say a 52-year-old mechanic from northwest Missouri holds one of the two tickets matching all six numbers in the record $588 million Powerball jackpot.
A Missouri Lottery news release says Mark S. Hill bought the winning ticket for himself and his wife, Cindy, at a gas station in Dearborn.
Another winning ticket was sold in the Phoenix area but that ticket holder has not come forward.
Dearborn is a town of about 500 located about 40 miles north of Kansas City.
The $587.5 million payout represents the second-largest jackpot in U.S. history.
